As of today, new temporary Covid-19 rules come into play which end the requirement to take a confirmatory PCR test following a positive Lateral Flow result.
Those testing positive from a Lateral Flow test now only need to self-isolate for 7 days so long as they test negative on days 6 and 7.
There are a few exceptions to this revised approach - please see below for more information.
